" What does real scientific work look like? As neuroscientist Stuart Firestein jokes: It looks a lot less like the scientific method and a lot more like "farting around … in the dark." In this witty talk, Firestein gets to the heart of science as it is really practiced and suggests that we should value what we don’t know -- or “high-quality ignorance” -- just as much as what we know.
Stuart Firestein teaches students and “citizen scientists” that ignorance is far more important to discovery than knowledge. " -- http://www.ted.com/talks/stuart_firestein_the_pursuit_of_ignorance.html
